The Treatment Process

Preliminary Treatment


The preliminary treatment process removes the debris and sandy materials from the used water. The used water arrives at the water reclamation plant (WRP) and is first lifted up to a higher elevation by pumps. With the help of gravity, the used water flows through the various treatment tanks and automated mechanical screens to remove the debris. This is followed by grit settling tanks or vortex grit chambers to settle and remove the heavier sandy materials present in the used water.
